Q.30-18
Question
Do the following electrocyclic reactions take place in a conrotatory or
disrotatory manner? Under what conditions, thermal or photochemical, would you carry out each reaction?
Step-by-Step Solution
Verified Answer
Theconditions under the reaction can also carried out then to check whether electrocyclic reaction will takes place in disrotatory and conrotatory manner also described.
1Reaction and condition for a
The reaction which involves 3 electron pairs. The reaction will do in the manner of disrotatory under thermal conditions.
2Reaction and condition for b
There are two hydrogen atoms in the product. There are 3 electron pair involved in the reaction. The reaction will takes place in conrotatory manner and carried out under photochemical conditions.
